Parasympathetic fibers in the vagus nerve
Parasympathetic fibers originate from the dorsal motor nucleus of vagus. They are distributed widely throughout the respiratory,gastrointestin al system and cardiovascular. GVM
vagus nerve
vagus nerve
• CN X • Start:brainstem
(medulla oblongata) • Distribute :
in the neck, thorax, and abdomen • Mixed fiba →jugular foramen → carotid sheath → on the side of mediastinum → esophgeal plexus → esophgeal hiatus → anterior and posterior vagal trunks
motor fibers in the vagus nerve innervates to the muscles of larynx and pharynx through the superior
laryngeal nerves and the recurrent nerves SVM
function
• This nerve supplies motor and sensory parasympathetic fibres to pretty much everything from the neck down to the first third of the transverse colon.
